90029: Broadcast 'CorrelationId' is empty

You sent a broadcast request with an empty CorrelationId value. Provide a non-empty CorrelationId so Twilio can associate the broadcast request with your application context.

• The CorrelationId field was included in the request, but its value was an empty string
• Your application trimmed or cleared the CorrelationId value before sending the request
• A variable used to populate CorrelationId was unset, null, or resolved to an empty value in your request-building logic

• Set CorrelationId to a non-empty string before you send the broadcast request
• Validate request payloads in your application so empty string values are rejected before submission
• Review any templating, serialization, or variable-mapping logic that populates CorrelationId
• If you do not need application correlation for this request, remove the field only if the API operation allows it. Otherwise, send a valid non-empty value
